使用 Python 和 bs4 在 Excel 中排列表格，因为它以 HTML 格式显示

Question

我已经成功抓取了一张我想在 .xlsx 中显示的表格

当它显示在浏览器中时，这就是我希望它在 excel 中显示的方式。

它应该显示的方式是

A1 = 1。

B1 = 准备协助与事件响应相关的行动和活动

C1 = 1.1

D1 = 确定事件响应的责任人和 WHS 立法要求

A2 = 空白

B2 = 空白

C2 = 1.2

D2 = 确定有关事件响应计划和报告的工作场所政策、程序和流程

下面是我的代码，后面是我抓取的 HTML。

for i in Elements.findAll('tr'):
    columns = i.findAll('td')
    output_row = []
    for column in columns:
        sub_rows = column.findAll('p')
        for row in sub_rows:
            output_row.append(row.get_text(separator=' '))
    Element_rows.append(output_row)

Answer 1

此示例使用re 和itertools.zip_longest 获取所需值并使用csv 模块编写文件（html_data 是您问题中的代码 sn-p）：

import re
import csv
from bs4 import BeautifulSoup
from itertools import zip_longest

soup = BeautifulSoup(html_data, 'html.parser')
tds = soup.select('td')

with open('data.csv', 'w', newline='') as csvfile:
    writer = csv.writer(csvfile, delimiter=',', quotechar='"', quoting=csv.QUOTE_MINIMAL)

    for td1, td2 in zip(tds[::2], tds[1::2]):
        cell_ab = re.findall(r'(\d+.)\s*(.*)', td1.text)
        if not cell_ab:
            continue
        cell_cd = re.findall(r'(\d+.\d+)\s*(.*)', td2.text)

        for (a, b), (c, d) in zip_longest(cell_ab, cell_cd, fillvalue=(None, None)):
            writer.writerow([a, b, c, d])

结果是文件data.csv（来自我的 LibreOffice Calc 的屏幕截图）：
